- Referring to
FIGS. 1-2 , anelectronic device 100, according to an exemplary embodiment, includes abody 10 and aninput device 20. In this embodiment, theelectronic device 100 is a mobile phone, although any other electronic device such as a game player is equally applicable while remaining well within the scope of the disclosure. - The
body 10 includes ashell 12, amain board 14, and arear cover 16. Theshell 12 is substantially an elliptical tube in shape, and defines anelliptical opening 122. Themain board 14 is a printed circuit board (PCB) received in theshell 12, and defines a substantially half-elliptical locking slot 142. Therear cover 16 has a similar shape to the opening 122, but is a little smaller than the opening 122. Therear cover 16 is electrically non-conductive, and includes anupper surface 162, abottom surface 164 opposite to theupper surface 162, and ahook 166. Thehook 166 has a similar shape of thelocking slot 142, but is a little smaller than thelocking slot 142. Therear cover 16 defines a circular throughhole 168 in the center. - Also referring to
FIG. 3 , theinput device 20 includes aresistor 202, awire 204, a conductingmember 206, a rotatingplate 208, acushion plate 210, afirst pad 212, asecond pad 214, athird pad 216, apower source 218, and ameasuring unit 220. - The
resistor 202 and thewire 204 each is a discontinuous ring in shape. The inner diameter of theresistor 202 is a little greater than that of the throughhole 168, and the outer diameter of theresistor 202 is a little smaller than the inner diameter of thewire 204. The resistance of thewire 204 is negligible when compared to that of theresistor 202, while the resistance of theresistor 202 is negligible when compared to that of themeasuring unit 220. The conductingmember 206 is a rectangular sheet in shape. The width of the conductingmember 206 is negligible when compared to that the circumferences of theresistor 202 and thewire 204, and the length of the conductingmember 206 is greater than the difference of the outer diameter of thewire 204 and the inner diameter of theresistor 202. - The rotating
plate 208 is made of a non-conductive material. Therotating plate 208 includes a circularupper plate 2082 and acircular bottom plate 2084 concentrically disposed on a bottom surface (not labeled) of theupper plate 2082. The diameter of theupper plate 2082 is a little greater than the outer diameter of thewire 204, while the diameter of thebottom plate 2084 is a little smaller than that of the throughhole 168. The thickness of thebottom plate 2084 is a little greater than that of the rear cover 16 (i.e., the depth of the through hole 168). Thecushion plate 210 is a circular plate made of a material with a high frictional coefficient, such as rubber. The diameter of thecushion plate 210 is a little greater than that of thethrough hole 168. - In assembly, the
resistor 202 and thewire 204 are concentrically disposed on theupper surface 162 and surround the throughhole 168. The first, second, andthird pads upper surface 162 and adjacent to theresistor 202 andwire 204. One end of theresistor 202 is connected to thefirst pad 212, and the other end is connected to thesecond pad 214. One end of thewire 204 is connected to thethird pad 216. The anode of thepower source 218 is connected to thefirst pad 212, and the cathode of thepower source 218 is connected to thesecond pad 214. One end of themeasuring unit 220 is connected to thesecond pad 214, and another end of themeasuring unit 220 is connected to thethird pad 216. The conductingmember 206 is disposed on the bottom surface of theupper plate 2082 adjacent to thebottom plate 2084. - Further referring to
FIGS. 4-5 , thebottom plate 2084 is inserted through the throughhole 168 from theupper surface 162. Theupper plate 2082 covers theresistor 202 and thewire 204. The conductingmember 206 keeps connecting theresistor 202 and thewire 204. Then, thecushion plate 210 is fixed to thebottom plate 2084, such that thecushion plate 210 and therotating plate 208 are rotatably connected to therear cover 16. Finally, therear cover 16 is engaged with the opening 122 so that thehook 166 hooks into thelocking slot 142. - In operation, the
electronic device 100 is placed on a platform (not shown). Thecushion plate 210 contacts the platform. Then, thebody 10 is pressed against the platform and rotated relative to the platform. As a result, thecushion plate 210 and therotating plate 208 remain still on the platform due to a friction between thecushion plate 210 and the platform. Theresistor 202 and thewire 204 rotate relative to therotating plate 208 with thebody 10. Accordingly, the conductingmember 206 moves around theresistor 202 and thewire 204. As a result, a voltage between thesecond pad 214 and thethird pad 216 varies according to formula (I): -
- where V0 is an output voltage of the
power source 218, R0 is a resistance between two ends of theresistor 202, RX is a resistance between thesecond pad 214 and the conductingmember 206, VX is a voltage between thesecond pad 214 and thethird pad 216. Themeasuring unit 220 measures the variation of VX which depends on the rotation of thebody 10. For instance, if thebody 10 rotates clockwise, theresistor 202 and thewire 204 rotate clockwise, and VX increases. Otherwise, theresistor 202 and thewire 204 rotate counterclockwise and VX decreases. Then, VX is inputted to a controller (not shown), and the controller can control the motion of a cursor on a display of theelectronic device 100 based upon VX. - It should be understood that the inner diameter of the
resistor 202 also can be greater than the outer diameter of thewire 204 to surround thewire 204. - It should be mentioned that the
power source 218 can be omitted. For example, in another embodiment shown inFIG. 6 , a measuringunit 220 a is interconnected between afirst pad 212 a and a third pad 216 a to directly measure a resistance between thefirst pad 212 a and the third pad 216 a, and a controller (not shown) can control the motion of a cursor on a display based upon the measured resistance. - It is to be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosures are illustrative only, and changes may be made in details, especially in matters of arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
